I have designed a Cardbus Card with Spartan 3 and Xilinx PCI Core, which works very well in all kind of notebooks, but when I try to use the card within a PC (with a PCI CardBus adapter card - TI PCI-1520 chipset) nothing happens not even the new hardware window comes up. But the PCI CardBus adapter seems to be OK, because if I use a bought 3COM Ethernet Card the new hardware window appears and the driver will be installed. The PCI Cardbus adapter card has exactly the same chipset as one of my test notebook, where the card is working very well. I have also tried to set the boot clock (CCLK) to maximum speed - but the result did not change. I do not really see the difference between a chipset mounted directly on the motherboard and the adapter card.
I hope somebody has an idea to solve this problem.
With kind regards Nico Presser
